Redrock Micro Cobalt Cage overview

  • 1Description

The Redrock Micro Cobalt Cage for GoPro HERO3 / HERO3+ / HERO4 is designed to protect your GoPro action camera from falls, bumps, and crashes. The GoPro attaches into the Cobalt Cage, and in the case of the camera can be used with or without the GoPro original underwater housing. The optional Redrock Micro Deluxe Accessory Kit allows you to attach the camera without its underwater housing, which eliminates the possible fogging that can plague your video and still shots, while still keeping the camera and its optics protected. In contrast to the one mounting point of GoPro's housing, the Cobalt Cage provides 22 different 1/4"-20 threads that surround the camera in all 360°. This allows you to use the Cobalt Cage to attach a variety of GoPro camera accessories.

The lightweight 6.5 oz Cobalt Cage features a reinforced high tensile design, and it's made of military-grade aluminum. This makes it impact-proof, crash-proof, and crush-proof. The multiple mounting points also allow you to mount the GoPro using a true triangulation method, which minimizes vibrations by providing stable and secure mounting. You can also expand your arsenal of mounting options with support rails, suction cups, clamps and more. You can under-sling or side-sling the camera as well, which will help you capture perspectives that would be otherwise impossible to capture with just the GoPro stock underwater housing.

Note: For use with the HERO3+ and HERO4 the Dive Housing is required. The original HERO3 housing (which is the same as the Dive Housing) is compatible.

Cobalt Cage can be used with the Dive Housing or Skeleton Frame. In addition, the camera can also be used withount any housing when employing the optional Deluxe Accessory Kit
Full cage coverage provides a protective design that's impact-proof, crash-proof, and crush-proof
Secured by six points of contact, which means you won't have to rely on just a finger mount
Provides 22 different mounting points on all four sides for rigging and accessories
Cobalt Cage is compatible with all GoPro camera add-on accessories
Cobalt Cage affords full access to all GoPro ports, switches and card slots

    Redrock Micro Cobalt Cage reviews

    Cobalt Cage for GoPro HERO3 / HERO3+ / HERO4 is rated 4.0 out of 5 by 8.
    Rated 3 out of 5 by from is good, but has details ... I bought the Cobalt Cage for a GoPro Hero 3 and the parts are very good quality. I can notice that it is solid and a good choice for use in extreme conditions.Missed though, that does not come with instructions to assemble optional parts, and also one of the screws was bigger than the hole, which was very unpleasant.

    Rated 4 out of 5 by from Solid fit, great for naked GoPro Sturdy well built cage with more than a dozen 20 mounting points for attaching accessories, or to a mounting arm. The accessory kit is a must if you want to operate the GoPro naked, i.e. without its plastic case. Kit comes with allen wrench and screwdriver, the Hero 3 and 3+ are very secure in this unit, I don't know what other reviewers are referring to when they complain about this mount, its rock solid. Make sure you order the correct one, RedRock makes one for the Hero 2 as well and its a different form factor will not fit the Hero 3. Cage provides easy access to the camera's HDMI, USB and microSD slot, so you can rig the GoPro with an external HDMI monitor if the camera is locked down for a shot. Cage provides extra protection for more demanding situations.

    Rated 5 out of 5 by from Love It I ride my mountain bike with my GoPro all the time. Before I had this I took a crash on my bike and the GoPro mount broke and sent my gopro off into a river.Now I use this and the metal ball clamp from them and the camera stays put no matter how bad of a dive I take.It's paid for itself tenfold compared to the amount of cameras I could have lost. I like this cage the best because I can still replace the battery without any tools. I've even done it while still riding along a trial haha.

    Rated 5 out of 5 by from A must have for GoPROS! This is the must have cage if you want to use your GoPro in any sort of real production environment. Always hated the GoPro mounting foot, it was too flimsy and it would even move on some of the harder impacts my camera had, pretty much ruining the shot, and those are always the shots you want! I also love that you don't need tools to get the camera in and out of the cage for battery changes, because we all know how often that happens with the GoPro 3's! I ended up getting the extra accessory kit later so I could mount the camera without the underwater housing for better audio. That works well, but it requires tools so I ended up just using it without the backgaurd thing which blocks the battery door, so now I could still switch batteries toolessly. There is no better way to attach your GoPro to stuff and stuff to your gopro than this!

    Rated 3 out of 5 by from Great Cage does not work with Hero 4 standard water housing The Redrock website lists the Hero 4 as one of the cameras that will fit in this cage with the diving housing. However the diving housing that will work is not the standard one that comes with the hero 4 black. It is the gopro AHDEH-301 that they say fits in the cage. That is an additonal $ dollars for that housing. Not happy with redrocks incomplete description for what is required. The cage itself is really well built. I am going to buy the extra diving housing. will revise my review after i receive it and give it a try.

    Rated 5 out of 5 by from Great product! I'm very impressed with the Cobalt Cage for my GoPro Hero4 Silver. I use the Hero4 in the GoPro Dive Housing with the Battery BacPac. When I first received the Cobalt Cage, the camera and dive housing didn't seem to fit into the cage and I was ready to send it back. Redrock Micro told me to remove the small metal plate on the bottom of the Cobalt Cage before inserting the dive housing. That worked like a charm. After inserting the camera in the dive housing into the Cobalt Cage, I re-installed the metal bottom plate. The camera and dive cage are very securely mounted and there is no movement. Not only is it extremely strong, but there are many mounting points on the Cobalt Cage. I mount the Hero4 on the outside of an airplane and I've always been concerned about the plastic fingers molded into the GoPro housing not being strong enough to withstand turbulence or strong air pressure at fast cruise speeds. Mounting the Hero4 on the outside of an airplane is also tricky since there are few secure mounting points that allow flexible orientation of the camera. The Cobalt Cage solves all those problems and dramatically improves the protection of the camera. The cage is very well made and precisely machined with excellent fit and finish. The Battery BacPac rear door protrudes out the back of the cage more than the standard door so I don't think that I'd be tempted to run over that side of the cage with a car but it works great on an airplane. I know this sounds like a commercial for the Cobalt Cage but it isn't. I've just been looking for something like this for a while and I'm very happy to have finally found it.

    Rated 2 out of 5 by from Another poorly fitting item from Redrock The cage itself is not bad. The fingers on the attachment that should fit a standard GoPro mount are too thin. They wobble which makes them virtually useless. I needed to add 4 shims to get a proper fit. It's not that the built quality is poor it's just that the item doesn't properly fit.
    Date published: 2014-04-11
    Rated 5 out of 5 by from Well Made and Well Designed The GoPro Hero 4 Black in its underwater housing fits perfectly in the Cobalt Cage. The housing looks so good and is so well made, you might not want to use it. Alas, this accessory is a must for mounting the GoPro to the exterior of a car, or on a bike. Although there are numerous ways to mount it, the cage does not include the GoPro mount.
